As a master of potions, everyone's preparation habits and research directions are always different. Snape, for example, was more adept at concocting potions with more elaborate steps, and the more skillful the preparation process, the more it set him apart from ordinary potions.

Slughorn, a veteran Potions Master, is clearly known for his extensive study of various Potions theories, as well as his solid skills through extensive preparation experience.

Just by looking at the various theoretical and practical techniques that he would mention from time to time in the course of his lectures, and the ease with which he came to them, it is clear that his knowledge of potions was extremely impressive.

“…… One last thing, yes! Professor McLean also mentioned the Ariot blade just now, and I believe you have been exposed to it in the past courses. So, can anyone help me recall this material? ”

Slughorn first explained the specific effects of vitality tonics, and by the way, he also appropriately named the characteristics of some of the main raw materials. After that, he began the first question of the class.

Needless to say, our Miss Granger had already raised her hand in the air.

In fact, she had almost given up on the option of raising her hand to speak in Snape's class, after all, no matter how much she raised her hand, Snape would ignore it, and she would not get any benefit at all except a sore shoulder. Even Hermione, who was as active in her studies, dispelled the urgent need to answer questions to add points to the house in the years of Potions class.

But now, she can raise her hand in Potions class again! It's more refreshing than sipping a warm butterbeer in Hogsmeade.

"Oh, Miss Granger?" Slughorn smiled at her and nodded.

"The Ariott tree, often referred to as the hyena tree, has leaves that induce hysteria and irrepressible laughter. For this reason, chopped Ariot leaves are often used to make 'Elixir of Laughter', which is one of its main ingredients. Moreover...... The molasses produced by the heartworm eliminates the symptoms of this leaf and requires only a small spoonful. ”

"Well, that's right," Slughorn said with satisfaction, "and even I couldn't have said better. However, as an endangered species, the molasses produced by the heartworm has become quite expensive, so I hope you can pay attention to this. ”

After this small reminder, he continued with what he had just said.

"Yes, everybody heard—the Ariot leaf makes people laugh, which is why it was the basis for the invention of the Elixir of Laughter. But in fact, the vitality tonic we are now learning about needs it as well, because its laugh-making effect is based on the extra vitality it can provide. ”

Slughorn paused and chuckled, "Professor Severus Snape, who taught you Potions in the past, is also quite a famous Potions Master in the wizarding world, and I think he must have specifically mentioned it when he taught the Potions of Laughter - during the preparation process, the chopped Ariot leaves should not be stirred too vigorously during the mixing process, otherwise the laugh-inducing ingredients in them will be destroyed!" ”

"But this time, we're just going to destroy it, because we don't want to laugh at someone else while taking the vitality tonic, do we? On that note, keep the difference between the two potions firmly in mind – I mean. If you get more points in the LS exam. ”

He shrugged his shoulders to show that he was thinking of everyone.

"So, the process of preparing the vitality tonic is relatively simple, and one of the hardest points is stirring when putting in the chopped Ariot leaves. Stirring vigorously destroys the laugh-inducing ingredients, and also creates a relatively large mana vortex reaction. Although Professor McLean has prepared white stamens for you, I hope you will need to be careful in the process of preparing them......"

Slughorn's so-called "magic vortex reaction" simply means that the liquid with magic power in the crucible forms a magic vortex because the stirring speed is too fast. If this reaction, which is more common in potion preparation, happens too violently, the sad fryer phenomenon will occur.

As can be seen from Luna's mother's death, the process of studying spells can sometimes be fatal. In the same way, there are some very terrible things that can happen during the preparation of potions.

And among the many accidents that are difficult to prevent, the fryer can be said to be a baptism that every potion preparer will experience. If you haven't fried a potion, you're too embarrassed to tell someone that you can make potions.

However, even if this kind of accident will follow you for the rest of your potion-making career, it will always be a bad accident that is better not to happen if it doesn't happen. Because depending on the potion you make, its danger cannot be generalized.

At the beginning, the world's most famous magic school potions tournament was permanently suspended because of a fryer in a certain final. According to the history of magic, the scene of that match was particularly tragic, and even left a poisonous swamp in Northern Europe that cannot be completely eliminated to this day.

"Alright, then it's time for the appearance of the Professor McLean you've been waiting for!" Slughorn happily said, "Today, he and I will show you a collaborative preparation technique!" ”

The name of the technology sounded a little unfamiliar, and even Hermione, who had read a lot of books of various colors, shook her head under the gaze of several Gryffindors, indicating that she didn't know.

"You don't have to think too much, because this potion preparation technique has not been officially entered into everyone's textbook, so it can't be found in the list of potions skills." "However, as you may recall, your Professor McLean has won two annual Silver Prizes in Practical Potions Master, the academic journal of Potions, and one of them is a research paper on this very ingenious potions preparation technique!" ”

As he spoke, he suddenly leaned forward and whispered, "...... I thought, since you're a Hogwarts student, why don't you be one step ahead of the students from other schools? ”

Since ancient times, potion preparation has often been the work of a single person. Although two-person cooperation will greatly reduce the difficulty of preparation in theory, when you try it in practice, you will find that there will actually be more interference with each other. Potions is a very delicate discipline, so this distraction is often fatal to a pot of potions.

But Maca, however, found a lot of preparation techniques that could be split in the process of personal preparation, especially those complex skills that required multi-purpose, which he had dismantled into simpler two-person cooperation techniques.

There is no doubt that this set of preparation technologies that are standardized because of splitting and summarizing will certainly make the preparation of some agents simpler and more conducive to the development of popularization.

"Actually, I didn't expect that the summary paper that I handed to Professor Snape at that time would be taken by Professor Dumbledore and submitted," Marka spread her hands and said with a smile, "If you have any special ideas in the future, remember to write them down and show them to your Professor Slughorn, maybe you can also win an award by the way?" ”

With that, he and the old man stood face to face on either side of the crucible in front of the classroom, and then Slughorn stretched out his wand and tapped lightly on the edge of the cauldron. On the other hand, Maca reached for the silver knife on the round table and quickly and neatly sliced a crumpled brown dried fruit.

Both of them are very familiar with the difficult potion of vitality tonic, and they know every step and every detail in their hearts. According to the technical split summarized by Maca, the movements of the two people did not lag in the slightest, and their respective division of labor became quite clear and smooth.

Slughorn's assessment of Maca's technique was accurate - it was an ingenious potion preparation technique, as it wasn't so advanced that even the students could easily understand most of the tricks.

Sometimes that's the case in academics, whether it's Muggle science or wizarding magic, where progress often begins with a humble summary. However, the establishment of another type of standardization will open up a new world for the entire discipline.

Everyone watched Maca and Slughorn cooperate tacitly, and you went back and forth clearly, and easily completed the whole first step - the preparation of the raw material base liquid. In the case of independent preparation, it can't be so light, and anyway, this is a potion that can only be learned in the fifth grade.

"Professor!"

As Slughorn put down the glass rod in his hand, and was about to analyze some of the techniques he had just demonstrated, a voice made him stop the words that had already reached his lips.

"Mr. Longbottom?" The old man asked curiously, "What's the matter?" ”

Neville, who had been very introverted since childhood, suddenly raised his hand to speak, which was big news, and most of the students now turned their heads to look at his table, so that Harry, Ron, and Hermione, who were at the same table as him, were surrounded by surprised eyes.

“…… Pan, Pansy Parkinson...... Miss, stuff me with a ball of paper......" Neville stumbled with his not-so-sharp mouth.

"What's written on it?" Slughorn raised an eyebrow, a hint of doubt flashing across his chubby old face.

It's not uncommon to pass around a few notes in class, and the old man is obviously not a strict professor, so he doesn't care much about these little actions.

"I haven't ...... yet Didn't look at it. Neville spread his palms and moved to the side as if trying to move farther away from the snakes.

Maca casually glanced at Parkinson's at Slytherin House, only to notice that her face was a little pale.
